In one exemplary embodiment, a gastric band is provided having a first end and a second end that mate to one another to encircle a stomach. A latch mechanism can be formed on the band, and at least one actuator can be coupled to the latch mechanism and it can be adapted to expand and contract the latch mechanism when energy is applied thereto to adjust a diameter of the band. In one exemplary embodiment, the actuator(s) is an electroactive polymer actuator.

摘要： A system for manipulating a heart during cardiac surgery permits coronary surgery on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the system. A component of the system engages the heart with a head of a heart positioning device, repositions the heart into a displaced position and maintains it in the displaced position while the heart continues to beat with substantially unabated and uninterrupted cardiac output. A select portion of the heart in the vicinity of a target area is immobilized to facilitate a surgical procedure to be performed at the target area. One form of the system can be used in minimally invasive surgery.

摘要： Devices and methods are disclosed for stabilizing tissue within a patient's body during a surgical operation to provide a relatively motionless surgical field, such as during a coronary artery bypass graft procedure. The devices include tissue stabilizers which engage and provide stabilization to a targeted area of tissue and further have the ability to engage and manipulate some portion of tissue within or adjacent the targeted area to improve the surgical presentation of that portion of tissue. The tissue stabilizer typically has one or more stabilizer feet which have a first foot portion configured to provide stabilization to the targeted tissue and a second foot portion moveable relative to the first foot portion for manipulating a portion of tissue to improve the surgical presentation.

摘要： Methods and devices are provided for controlling movement of a working end of a surgical device. In one embodiment, methods and devices are provided for moving an end effector on a distal end of a surgical fastening device. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e.g., closing, firing, and/or cutting. In other embodiments, a single cable actuator is provided and is movable between a first position, in which it is effective to rotate an end effector without actuating (i.e., closing and firing) the end effector, and a second position, in which it is effective to actuate the end effector without rotating the end effector. In other aspects, methods and devices are provided for moving a flexible neck formed on a distal end of an accessory channel for use with an endoscope. Movement of the flexible neck can be used to control positioning of a tool extending through the flexible neck.

摘要： A surgical instrument is disclosed. The surgical instrument includes a handle portion, a channel, an anvil, and staple cartridge, a wedge member, a reciprocating firing device, and a lockout arm. The handle portion is operably configured to produce a firing motion and is coupled to the channel portion. The staple cartridge is engaged by the channel and includes a plurality of staple drivers to cam the staples toward the anvil, which is pivotally attached to the channel. The wedge member is proximal to and longitudinally aligned with the staple drivers, and the reciprocating firing device is responsive to the firing motion to progressively drive the wedge member from an unfired to a fired position. The lockout arm is pivotally attached to the channel and operably configured to pivot between a locked position and an unlocked position with respect to the firing device based upon a position of the wedge member.
